# Photo Extender > A photo extender adds new picture around your photo so it fits a different shape without cutting anyone out. To expand a photo on Kenerate, upload it to Expand Image, pick the shape you need — 9:16 for Stories and Reels, 4:5 for portrait posts, 16:9 for YouTube — and choose where the original sits.

Open Expand Image and add your photo — Upload from your camera roll or computer: JPG, PNG or WebP up to 25 MB. Sign in with a verified email to run it. 2. Pick the shape you need — 9:16 for Stories, Reels and TikTok; 4:5 for portrait posts; 1:1 for square; 16:9 for YouTube and desktop. A shape your photo already has is blocked. 3. Place the photo — Choose left, centre or right (or top, centre, bottom), or drag the photo inside the frame, so the new area lands where you want it. 4. Extend and save — Optionally say what the new area should show, run it, and download the result without a watermark. Ask for 2 variations if you want a choice. ## In depth ### Why do my photos get cropped when I post them? Each app shows pictures in a fixed set of shapes. Your phone shoots 3:4 or 4:3, a full-screen Story or Reel is 9:16, a YouTube thumbnail is 16:9. When the shapes don't match, the app either crops your photo or pads it with bars. Extending the photo to the target shape first means you decide what's in the frame. ### Which photos extend best Photos with a simple surrounding — sky, sea, a plain wall, a studio backdrop, a park — give the model an easy pattern to continue. Busy scenes still work, but check the new area for doubled objects. If someone's arm or bag is cut by the edge, the model has to invent the rest, so try Nano Banana 2 or a second variation. ### When cropping is still the better choice If the target shape is narrower than your photo and the subject sits in the middle with nothing important at the sides, cropping is faster and keeps every pixel real. Extending wins when the subject fills the frame or sits off-centre, and when you need extra space for text. ### Extending a photo on your phone Expand Image runs in the mobile browser, so there's nothing to install. Upload from your camera roll, pick the shape, tap to place the photo, and save the result back to your phone. The same account works on desktop, and your results stay in your History. ### Whose photos should you extend? Your own photos, or pictures you have the rights to use. Extending changes a photo by adding invented content, so be careful with photos of other people: don't present an extended photo as an untouched record of a real event. ## FAQ Q: Is there an image extender I can use free? A: You can try Kenerate's photo extender without paying: new accounts get starter credits, and there's no subscription required. After that you buy credits only if you want more runs. There is no plan gate, every model is available to every account, failed runs are refunded automatically, and results download without a watermark. Q: How do I expand a photo for Instagram Stories or Reels? A: Upload it to Expand Image and pick 9:16, the shape labelled for Stories, Reels and TikTok. For a horizontal photo, the tool grows the top and bottom; choose top, centre or bottom to decide where the new area goes. Optionally describe it, such as 'more sky above, more sand below', then download. Q: Can I extend a photo on my phone? A: Yes. Expand Image works in the phone browser with nothing to install: upload from your camera roll, pick a shape or grow the edges, place the photo and run it. Results save to your device without a watermark and also stay in your Kenerate History, so you can open them later on a computer. Q: Will the person in my photo change? A: The original photo is kept where it is; only the new area is painted. The tool's instruction tells the model to keep the photo's content, position and scale unchanged. Models can occasionally retouch near the seam, so check faces at the edge, and pick Nano Banana 2, which the tool lists for keeping faces consistent. Q: Why is my extended photo smaller than I expected? A: Because each model answers at its own size: GPT models at 1024 px square or 1536 px on the long side, Nano Banana 2 at about 1 MP, Nano Banana 2 Fast at about 4 MP. For a large print or a 4K screen, send the result to Upscale from the result screen. Q: Can I make a photo wider on just one side? A: Yes. Switch to Grow edges and set only the side you want, from 0 to 100% of the photo's width or height in 5% steps. That is handy for adding space next to a person for a caption, or extending only the sky. The presets +10, +25 and +50% grow every side at once. ## Related pages - AI Image Extender: https://kenerateai.com/ai-image-extender - Uncrop Image: https://kenerateai.com/uncrop-image - Photoshop Generative Expand alternative: https://kenerateai.com/photoshop-generative-expand-alternative - AI Image Upscaler: https://kenerateai.com/ai-image-upscaler - Image to Video AI: https://kenerateai.com/image-to-video-ai ## Sources - Kenerate Expand Image: https://kenerateai.com/app/tool/expand-image
